  • Patent number: 11774284
    Abstract: A high-sensitivity light sensor includes a light sensing element, a first integrator, a comparator, and a second integrator. The light sensing element senses a light during a measurement time interval to generate a current. The first integrator integrates the current to generate a first integration signal. The comparator compares the first integration signal with a threshold value. While the first integration signal is greater than the threshold value, the comparison signal is at a first level. The second integrator is coupled to the first integrator and integrates the first integration signal to generate a second integration signal. The light sensor of the present invention uses two integrators to integrate the sensed voltage twice. Therefore, the light sensor of the present invention has a higher sensitivity.

    Abstract: A load regulation device, such as an LED driver, may be configured to control the intensity of a light source based on an analog control signal and a preconfigured dimming curve. The LED driver may sense a magnitude of the analog control signal and determine a new low-end and/or high-end control signal magnitude that falls outside of the input signal range of the dimming curve. The LED driver may rescale the preconfigured dimming curve according to new low-end and/or high-end control signal magnitudes and dim the light source based on the rescaled dimming curve. Multiple LED drivers controlled by the same analog control signal may communicate with each other regarding the magnitude of the analog control signal sensed by each LED driver, and match their target intensity levels despite sensing different analog control signal. A controller may be provided to coordinate the operation of the multiple LED drivers.

  • Patent number: 11437219
    Abstract: Frequency tuning for a matchless plasma source is described. To perform the frequency tuning, current is measured at an output of an amplification circuit of the matchless plasma source after a change in a frequency of operation of the matchless plasma source. Upon determining that the current has increased with the change in the frequency of operation, the frequency of operation is further changed until the current has decreased. When the current has decreased, the changed frequency of operation is further modified to be an operational frequency. When the matchless plasma source operates at the operational frequency, the current at the output of the amplification circuit is maximized.

  • Patent number: 11324089
    Abstract: Introduced here are techniques for generating color mixing models that enable a tunable lamp to mix the right amount of light from various color channels in order to properly produce colors. More specifically, a lamp controller can be configured to drive multiple light-emitting diode (LED) arrays based on corresponding color mixing models. One or more color mixing models can be provisioned into the memory of an LED array prior to usage. Storing the color mixing model in the LED array enables the lamp controller to update the color mixing model based on which LED array it is serving (i.e., the lamp controller and the LED array need not be a permanently matched set). Additionally or alternatively, the lamp controller may be configured to communicate with a network-accessible computer server system to access a historical color mixing database that includes set(s) of previously-recorded spectral properties and corresponding color mixing models.

The control circuitry is configured to receive one or more ambient light level measurements corresponding to the amount of ambient light detected by an ambient light sensor, and determine a range of values for the one or more ambient light level measurements corresponding to a desired amount of light detected by the ambient light sensor. The control circuitry is then configured to drive the solid-state light source such that the one or more ambient light level measurements received from the ambient light sensor fall within the determined range of values.

  • Patent number: 10902718
    Abstract: A wireless control device may include a housing, a yoke, an antenna, a communication circuit, and a control circuit. The yoke may be electrically conductive and be configured to mount the wireless control device to an electrical wallbox. The antenna may be configured to transmit and receive radio frequency signals. The antenna may be a slot antenna. The communication circuit may be configured to transmit and receive the radio-frequency signals via the antenna, and the control circuit may be responsive to the communication circuit (e.g., the signals received via the communication circuit). The control device may also include a conductive component that is attached to a front surface of the housing. For example, the conductive component may be electrically connected to the yoke via a single electrical connection (e.g., a screw). Further, the conductive component may be parallel with the antenna and configured to be capacitively coupled to the antenna.

  • Patent number: 10887970
    Abstract: A daylight harvesting system includes a daylight harvester device that distinguishes the natural and artificial contributions to the light in a workspace. Distinguishing the contributions allows the values of the contributions to be combined in ways other than linearly summing them to obtain the total light. For example, when the natural light increases, the artificial light may be reduced by less than the natural-light increase to mitigate glare and/or shadows and other artifacts that might otherwise be present and objectionable. The daylight harvesting system can include a human-based sensor located in a workspace, e.g., on or close to a user, so the measurements it takes are not adversely affected by spatial variations across a room in the natural and artificial lighting.

  • Patent number: 10826250
    Abstract: A power cord is described that includes “in-line” power control functionality. The power control functionality may selectively enable or disable a flow of electrical current through the power cord and/or selectively control an amount of electrical current that is permitted to flow through the power cord. The power control functionality may be activated and/or controlled through the receipt of control signals from an external device. The power cord may be configured to monitor the state of an electronic device to which it is connected and selectively activate and/or modify the operation of the power control functionality in response to the detection of a particular state of the electronic device. The power cord may also be configured to receive and analyze sensor data, and based at least on the analysis, selectively activate and/or modify the operation of the power control functionality.
